Seelye’s Welding Safety Instructions

Seelye’s Welding Safety Instructions

Follow Seelye’s step-by step instructions, as well as those issued by the manufactures of the plastic materials, you will be welding. Hot air welding is safe because there is no flame, spark, or smoke involved. Special venting, hoods, and ducting are not required. Observe these simple rules.

  1. Never attempt to perform hot air welding with a flammable gas.
  2. To avoid burning out the heating element, always remember Air Flow First and Air Flow Last. Start the air flow before the heating element. Set the air flow at 3-1/2 to 4 PSI to prolong the life of the element.
  3. Never touch metal parts on the welding gun until they have cooled.
  4. Always use a pliers to change the tip on a welding gun. (Do not overtighten).
  5. Disconnect the electricity to the gun but continue the air flow. The gun will cool faster and the electric heating element will last longer.
  6. Do not put the welder in a vise to change heating elements.
  7. Keep away from children. Warning: Do not use near flammable products. Tips are hot - Do not touch! Some barrels are extremely hot- Do not touch!
